The talk show host tackled this topic on "The View" Wednesday -- this a day after the Republican presidential candidate went on FOX News to rebuke the notion that America is a racist nation ... but in the same breath, denied the U.S. has ever that problem.

Of course, that's a ridiculous statement ... and just factually wrong. Not only did we have slaves in this country for a good long while -- but America was a segregated nation through much of the 20th century as well. Basic history ... but NH seems to be trying to blur it.

Welp, Whoopi wasn't having any of Haley's obfuscation ... and she unloaded on her in no uncertain terms in an impassioned speech as she was intro'ing this topic at the table.

Check out what she has to say for yourself -- she says all the lynching of Black people over the years wasn't carried out by them ... but by racist Americans, and you can tell she's outraged by Haley's attempt to downplay this country's past.

The reason this latest slip-up from her stands out is the fact that just recently suggested the Civil War was not really about slavery -- something she tried to clarify after the fact ... but raised a lot of eyebrows when she said it.

Things didn't get better when she further tried distancing herself from those remarks at a Republican town hall ... using the old "I have Black friends" line to defend herself.
